Switch - Cable Diagnostics

The Cable Diagnostics feature helps identify any connectivity problems with cabling and provides information about where errors may have occurred. The tests utilize Time Domain Reflectometry (TDR) technology to assess the quality of a copper cable connected to a port. TDR works by detecting cable faults through the transmission and analysis of a signal sent through the cable. However, the TDR may yield different results based on the status of the port, and these results must be interpreted accordingly.

The SFP (Small Form-factor Pluggable) port is not supported in this feature.

  2. Click on the Cable Diagnostics tab.

  3. Select any port and click Test to view the results in the Result box. The result displays the local pair's status and length of the cable.
